Abstract

 As a fundamental study for establishing numerical analysis technology that can compute dynamic interactions between tsunamis containing suspended sediment, behavior of coastal protection facilities, seabed profile change such as local scouring, and seabed response, parameters of an evaluation equation for the viscosity of a fluid containing suspended sediment were identified from laboratory experiments using a viscometer. It was confirmed that while clear water was a Newtonian fluid because its viscosity was independent on the shear stress, muddy water containing suspended sediment was a non-Newtonian fluid because its viscosity decreased with an increase in the shear stress. Furthermore, it was found that once suspended sediment concentration and shear stress are given, the viscosity of the muddy water can be determined from the evaluation equation using the identified parameters.
